Embedded 2G/NB-IoT Co-deployment with 4G/5G LTE

Abstract

In a first embodiment, a method is disclosed, comprising: determining when and where to create a 2G/Narrowband-Internet of Things (NB-IOT) carrier at a 2G base station; starting up the 2G/NB-IOT carrier; creating an interference-free zone for a co-located 4G or 5G carrier co-located with the 2G base station; turning off the 2G/NB-IOT carrier; and reverting the interference-free zone. The method may further comprise embedding one or more 2G/NB-IOT carriers in a guard band of 4G/5G. The method may further comprise transmitting a 2G/NB-IOT carrier from a co-located base station. The method may further comprise using Self-organizing Network (SON) information to determine when a 2G/NB-IOT carrier should be started or shut down. The method may further comprise shutting down a 2G/NB-IOT carrier after use. The method may further comprise creating interference free zones in required regions of the spectrum. The method may further comprise creating interference free zones using a Relative Narrowband Transmit Power (RNTP) Information Element of a X2AP protocol. The method may further comprise creating interference free zones across multiple neighboring eNBs.
